Types of lighting
Lighting is a very technical area and there are many types of lights (or lanterns). Coloured gels can be added to the front of some lanterns so that they throw coloured light onto the stage. Some can also be fitted with what is known as a gobo. This is a sheet inserted on a frame at the front of the light with a design cut into it. It filters the light, creating a picture effect on the stage. For example, a gobo could be used to create a dappled lighting effect to look like the leaves of a forest, or could be cut to create strips of light onstage which look like the bars of a prison.
Spot - has a hard-edged effect, used to light characters or elements on the stage. Coloured filters can be used with this lamp.
Fresnel - used for a softer edged effect, with a diffusing lens in front of the lamp. It's useful for good overall light when used with others. Coloured filters can be used with this lamp.
Flood - produces a clear wide-angled light, but there’s little control over the spread of the light. Coloured filters can be used with this lamp.
Strobe - a flashing light, used for special effects. It’s often used to give the effect of old movies. It produces a jerky effect on the movements of actors when used on its own.
